These settings are in the 'Lock screen and security' section, under SECURE LOCK SETTINGS. There, also check the time it takes for your phone to lock automatically after a screen off event or after you press the power key.
It wasn't secure lock settings, I don't have anything "on" in that section. Looks like it was the "secured lock time." It was set to 10 minutes by default and since I got the phone yesterday I've hardly put it down. That explains it. Thank you!
